In this article we present our new implementation of Real-time transport protocol (RTP) with its control protocol (RTCP) which enables the real-time delivery of continuous and interactive media over an emerging access network -Ethernet passive optical networks. RTP can provide end-to-end delivery service for data with real-time characteristics, such as interactive audio and video. While RTP is primarily designed to satisfy the needs of multiparticipant multimedia conferences, it is not limited to that particular application. Now we can use it for multimedia delivery over EPON, which represent the convergence of low-cost Ethernet equipment and low-cost fiber infrastructure, appear to be the best candidate for the next-generation access network. Ethernet passive optical networks are an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office (co) and a customer site. RTP application designers are advised to avoid mechanisms that can only work in unicast mode and will not scale to larger number. Because of some characteristics of EPON architecture, we develop a new RTP which is suitable for this architecture.
